Start of week 1, Novembers 1st. During the last couple weeks I had been dialing my system and setting up my sensor controller which is connected to a raspberry pi. I have a dashboard to view the status of the the environmental or control the lights/pumps/fans with the parts in place to eventually automate feeding and resevoir adjustments.
While I was doing that the plants suffered a bit but are recovering now. I switched the lights to an 11 on 13 off schedule and fed them to an ec of 0.8 or about 400 ppm.
@moeGrow,i know that sativa strains dont like hard feeding ,some take it ok but go easy,just in case ,i see some spots on leafs and some slight burns ,idk cause the light isnt good to distinguish colors if there are problems with the plant,in general a plant needs ph being stable not fluctuating.that can lead to problems

happy growin
@Blacklisted, I let the ph drift between 5.5 and 6.2 to allow for uptake of nutrients all the way along the range. As they eat it climbs higher, I've also increased their feed to 1.9 EC biggest part if that increase is the magnesium sulfate as they cant seem to get enough. Sativas generally dont like strong nutrients but these girls are pretty happy.
